The ambulance crew is part of first aid. As is the box on the wall. As is the non-medical person who uses something from that box on the wall to help. For all of them their primary purpose is to triage, and and then render get people to the correct needed care. Sometimes (often) the situation is minor and they can handle it, however their primary purpose is to get someone in trouble to better care fast. The ambulance crew has a few more tools to get you to the hospital fast, and some tools to solve emergency situations that most of us do not, but their primary job is still getting someone to a hospital.
